HELP ME PLS

Mathematics
1 answer:
Dafna11 [192]4 years ago
3 0

Answer: R' = (3\frac{1}{3} ,1\frac{2}{3}), S' = (3\frac{1}{3} ,-3\frac{1}{3}), T' = (-1\frac{2}{3} ,-3\frac{1}{3})

<u>Step-by-step explanation:</u>

R = (2, 1)  ⇒  R' = (\frac{5}{3})2 , (\frac{5}{3})1 = (\frac{10}{3} , \frac{5}{3})

S = (2, -2)  ⇒  S' = (\frac{5}{3})2 , (\frac{5}{3})(-2) = (\frac{10}{3} , \frac{-10}{3})

T = (-1, -2)  ⇒  T' = (\frac{5}{3})(-1) , (\frac{5}{3})(-2) = (\frac{-5}{3} , \frac{-10}{3})

Plot the coordinates.

The area of an equilateral triangle is LaTeX: 108\sqrt[]{3}\:ft^2 108 3 f t 2 . What is the length of one side of the triangle?
Temka [501]
The length of one side is 12√3.

We know that the area of a triangle is given by the formula:

A=1/2(b)(h)

We can substitute the area in:
108√3 = 1/2(b)(h)

Let b be the side of the equilateral triangle.  To find the height, we will use the Pythagorean theorem.  We know that the height bisects the base, so we will call that leg of the right triangle formed (1/2b).  Since the triangle is equilateral, we will call the hypotenuse b as well.  We now have:

(\frac{1}{2}b)^2+h^2=b^2&#10;\\&#10;\\\frac{1}{4}b^2+h^2=b^2&#10;\\&#10;\\\frac{1}{4}b^2+h^2-\frac{1}{4}b^2=b^2-\frac{1}{4}b^2&#10;\\&#10;\\h^2=\frac{3}{4}b^2&#10;\\&#10;\\\sqrt{h^2}=\sqrt{\frac{3}{4}b^2}&#10;\\&#10;\\h=\frac{\sqrt{3}}{2}b

We will now substitute this in the formula for area we had above:
108√3=(1/2)(b)(√3/2b)
108√3=√3/4b²

Multiply both sides by 4:
(108√3)×4=(√3/4b²)×4
432√3=√3b²

Divide both sides by √3:
432√3/√3 = √3b²/√3
432=b²

Take the square root of both sides:
√432=√b²

Simplifying the radical, we have 12√3.

Sociologists say that 85% of married women claim that their husband's mother is the biggest bone of contention in their marriage
hoa [83]

Answer:

(A) 0.377,

(B) 0.000,

(C) 0.953,

(D) 0.047

Step-by-step explanation:

We assume that having a bone of intention means not liking one's Mother-in-Law

(A) P(all six dislike their Mother-in-Law) = (85%)^6 = (.85)^6 = 0.377

(B) P(none of the six dislike their Mother-in-Law) =

(100% - 85%)^6 =

0.15^6 =

0.000

(C) P(at least 4 dislike their Mother-in-Law) =

P(exactly 4 dislike their Mother-in-Law) + P(exactly 5 dislike their Mother-in-Law) + P(exactly 6 dislike their Mother-in-Law) =

C(6,4) * (.85)^4 * (1-.85)^2 + C(6,5) * (.85)^5 * (.15)^1 + C(6,6) * (.85)^6 = (15) * (.85)^4 * (.15)^2 + (6) * (.85)^5 * .15 + (1) * (.85)^6 =

0.953

(D) P(no more than 3 dislike their Mother-in-Law) =

P(exactly 0 dislikes their Mother-in-Law) + P(exactly 1 dislikes her Mother) + P(exactly 2 dislike their Mother-in-Law) + P(exactly 3 dislike their Mother-in-Law) =

C(6,0) * (.85)^0 * (.15)^6 + C(6,1) * (.85)^1 * (.15)^5 + C(6,2) * (.85)^2 * (.15)^4 + C(6,3) * (.85)^3 * (.15)^3 =

(1)(1)(.15)^6 + (6)(.85)(.15)^5 + (15)(.85)^2 *(.15)^4 + (20)(.85)^3 * (.15)^3 =

0.047

I beg someone to answer ive posted this 3 times and im still not sure how to do it.....
Anni [7]

Answer:

D) 3 X 10⁷

Step-by-step explanation:

<u>Estimated days:</u>

  • Jan 2000 to June 2001 = 1.5 years = 365*1.5 days ≈ 548 days

  • 1 day = 24 hours = 24*60 minutes = 24*60*60 seconds =
  • 86400 seconds

  • 548 days = 548 * 86400 seconds =
  • 47347200 ≈ 4.7*10⁷

Best estimate is D) 3 X 10⁷
